The fifth generation of mobile networks, commonly known as 5G, holds a lot of promise. Historically, 2G brought us mobile voice, while 3G introduced us to mobile data. 4G and LTE enabled usable mobile broadband services and now 5G is supposed to unlock further value from our mobile networks with...

As operators prepare for 5G service launch around the globe, the industry has a reasonable view of how the initial generation of 5G products and services will look and is moving forward with confidence. What’s still unknown is just how great will be 5G’s global impact. According to a recent...

Originally conducted in the Spring of 2018, The TelecomTV 5G EVOLVED AND DEFINED survey highlights to what extent CSP/telco opinions depart from those of Network Equipment Providers (NEPs) and software vendors. The results underline major findings found by splitting respondents into two groups to compare side-by-side.

Male Voice: InterDigital's Millimeter Wave Hotspots are the 5G solution for longer-term wireless capacity growth, enabling backhaul and access throughput beyond what’s available with the emerging small-cell and spectrum-sharing solutions. Demand for wireless capacity is growing at an unprecedented rate, doubling in each of the last five years, according to one operator. At this rate, we could need 100X improvements by the year 2020, exhausting advancements that are becoming available through current spectrum-sharing and small-cell initiatives. By 2023 and beyond, we need to consider how to provide more than 1000X growth. And more spectrum, through higher-frequency Millimeter Wave bands is the answer. These advancements must be realized without raising costs. Typical Millimeter Wave Hotspot deployments include lampposts, strand mounting, storefront, as well as large public spaces, such as airports and malls. The Millimeter Wave Hotspot architecture is built upon three key innovative elements: electrically-steerable, phased-array antennas, which provide multidirectional coverage with higher gain; wireless backhaul, for enabling a high-capacity mesh network of small cells; and, finally, Millimeter Wave Hotspot access links, enabling gigabit data to our mobile devices. Our analysis and experimentation shows that it is possible to meet the 1000X capacity demand of the next decade with Millimeter Wave Hotspots covering approximately 150 meter ranges. Douglas Castor: InterDigital’s wireless research is driven by looking at the needs of next-generation systems. And early on, we saw the need to utilize higher-frequency spectrum. There is a historical trend of wireless moving to higher frequencies, and we didn’t see this stopping for 5G. So, we built a comprehensive set of research tools that allow evaluation of our Millimeter Wave architecture envision. And this year, we are presenting our Millimeter Wave Hotspot concept, along with our evolving platform. Daniel Steinbach: What we will now demonstrate is a three-node mesh network, using InterDigital’s Millimeter Wave technology. What we see is that the nodes are in discovery mode, where they’re trying to form a mesh network. At this point, node one has connected to node two, and now node three has just connected to node one, as well. And as soon as nodes two and three form a link, we will send pseudorandom data through the system, where data will be passing through all three nodes. And then, at some point, we will then break the link between nodes two and three, which will then reroute the data around the mesh network. At this point, all three nodes are connected, and we see, through quick graphs, are streaming data through. What we see here is, we see a relatively consistent RSSI throughput and uplink throughput, as well. And now we’re going to break the link between nodes two and three, and we see that the link is down, and that the throughput has gone up between nodes two, one, and three, simply because it’s rerouting the data that used to pass between two and three. We now reestablish the link between node two and three, and the data has gone back to its initial state. Male Voice: Millimeter Wave Hotspots are one of the ways InterDigital is leading the way with 5G research. Our platforms and technologies will soon be available for integration within the 5G research and industry community.
